Solid, liquid and gas
Solid Liquid Gas
Picture e.g
Arrangement Very closely packed Closely packed Very far apart
Regularly arranged Irregularly arranged Randomly arranged
Movement Vibrating in its xed Move throughout Move rapidly in all
positions container directions
Forces of attraction Very strong Strong Weak
Changes in matters:
Melting point: A xed temperature whereby a substance changes from solid to liquid state.
Freezing point: A xed temperature whereby a substance changes from liquid to solid state.
Boiling point: A xed temperature whereby a substance changes from liquid to gas state.
Particulate nature of matter:
1. Particulate nature of matters:
a. Particles possess kinetic energy, and are always in constant random motion.
b. Particles move at di erent speeds in di erent states.
c. Particles possess higher kinetic energy at higher temperatures.
d. Lighter particles travel faster than heavier ones.
2. Brownian Motion
- Smoke particles moving randomly, bombarded by air molecules to change
direction
